The problem is probably d/t virtualization.
I don't know why but when I enable SVM and hyperV, the box won't boot. |

Regarding virtualization problem: This is a known issue due to the buggy AGESA/Modules in the the last 2 BIOS updates that added ONLY the initial support for Zen+ (3x00G APU's).
So far, support in my tickets have stated that there are no plans to update the AGESA/Modules for this model, despite the fact that they literally have forum's full of people with issues. That said, create a ticket to suppport, maybe it will get them to at least change the tone to "we will update it to the latest when we have time" (and actually do it) which is even more acceptable then "nope, let it die with its KNOWN bugs"... BTW, they did release a 3.53 beta which fixed the issues (shocker, updated modules!) only to revert with 3.60... maybe you can get them to link you to it! It is what it is and I am responsible for 20+ of these in one way or another and ASRock has made my life a living hell... |

Hello J Z,
Have recognised that you have created a new BETA BIOS P3.60L thanks for that. But I must say that I am not brave enough to flash it, I would prefer official downloads from Asrock. Do not want to brick my A300. Has anyone else tested it? Does this support 4700g already? Thanks |

No JZ recommendation for the 3.60L, too many BUGs I noticed.
A new BIOS with AGESA V2 1002 will come. |

Hello,
I have the same problem. I have installed the last Ubuntu 20.10, but after the restart, the screen stays black. I clear the CMOS and a normal boot occurs, but the screen stays black again after the reboot. My config: MB: AS300W with the 3.6 BIOS APU: AMD Ryzen 5 3400G RAM: 2x16 GB Corsair Vengeance Storage: 1x Crucial P1 (CT1000P1SSD8) Does a beta version of the BIOS fix the issue? Best regards, djax |

After certain Grub updates on Linux Mint 19 I also experienced the black screen you are describing. Rolling back this Grub update fixed the issue but of course this cannot be your solution. Since I have flashed Beta BIOS 3.60K the problem is gone for months, it has never occurred again. Also the Grub Update was possible without any issues.
I recommend to use the latest Asrock Beta BIOS 3.60K as it fixes several issues including yours. My machine: A300, 2400G, 3.60K, 2*16GB Kingston, 2*NVME Samsung Drives |

Thank you.
![]() I unplugged the cables, cleared the CMOS, removed the nvme drive, put keyboard and power updated the BIOS to the 3.60K, unplugged the power, put back the nvme drive, plugged back the cables, start, restart and it WORKS!!! ![]() Have a nice day |

I have BIOS 3.60K and linux mint installed, and I have never experienced any problems with loading. Which BIOS version does the system fail to boot with?
The only problem that bothers me is errors when loading the kernel, "AMD-Vi: Unable to read / write to IOMMU perf counter" I enabled iommu = on and amd_iommu = on in the kernel boot parameters, and virtualization in the BIOS, but that didn't help .. 1.Advanced - AMD CBS - nbio common options - nb configuration - IOMMU Enable 2.Advanced - North bridge configuration - SR IOV Enable 3.Advanced - CPU config - SRVmode Enable cpu = Athlon 200GE |
